S.D. Codified Laws § 14-2-51 (2026)
All public library records containing personally identifiable information are confidential. Any information contained in public library records may not be released except by court order or upon request of a parent of a child who is under eighteen years of age. As used in this section, "personally identifiable" means any information a library maintains that would identify a patron. Acts by library officers or employees in maintaining a check out system are not violations of this section.
